She is a member of the Otogi Bank and cousin to the clubs president, Kiriki Liszt, or as she calls him, Li-kun. She is the "secretary" of the Otogi Bank. She most likely fits the ant description in Aesop's fable The Ant and the Grasshopper as she is shown working and usually in a serious manner. Because of this, she is not very good at running. Also, her hair's front resembles the antennae of an ant, and the first two syllables of her name, "Ari", is the Japanese word for "ant". She is 162cm tall.
